polynomial long division is useful if you don't have internet access or a scientific calculator on you
for my elementary teachers not bothering explaining to us
ah that
otherwise just put "solve <polynomial>" into wolfram alpha
So i still needa learn long division for calculus just incase?
yea that
The 34 then the division symbol then lets say 710
i mean
i think we did study polynomial long division but prolly forgotten bout it now tho
i find it quicker to just factorise each number lmao
ah well
Im on reverse ig
Standard long devision is based on polynomial long division in any case
I just multiply the divisir
Ah well shit
If you’re doing calc though I doubt you’ll ever need to do long division of normal numbers
do u need it for calculus?
the issue is that you kinda have to know common divisibility rules
I do dont worry
Ive been using this method for
6 years
but no you probably won't need long division lol
Well you should understand polynomial long divison at least
But regular you won’t
alright then, good call
Tyty
Ima stick with my whatever
its called
Im 100% someone made this method lol
I just dont know how to find and who
what's more active, this or the original discussion
who is the best math youtube channel?
in my opinion it is the organic chemistry tutor
he is a no bs no ego guy
This channel focuses on providing tutorial videos on organic chemistry, general chemistry, physics, algebra, trigonometry, precalculus, and calculus.

ew
wtf
there isn't a 'best' one imo
I watch a bunch, each for different reasons
i also do that each one teaches in a different way and you catch a couple of new things also in that way, but tbh the organic chemistry tutor is also not that bad he gives many exercises
I think most of them are meh. 3blue1brown is nice, but sometimes they dumb down concepts when what they are talking about deserves a tad bit more rigor or depth.
Numberphile has videos that are completely wrong sometimes too.
I didn't like 3b1b's linear algebra tho
i found his linear algebra fine
like it could seem intuitive and clear at first
it's expository introduction to lin alg
like?

The sum of all natural numbers (from 1 to infinity) produces an "astounding" result.

They say a divergent series is convergent upon rearranging the sum, despite the fact that the reason this is “true” is because of the analytic continuation of the Riemann Zeta Function
@junior hatch is it okay if I DM you
sure
Hi dumb question
if I have some process where I have some special sets marked
and throughout this process I unmark, and then some sets I mark again
is "remark" the word for marking something again?
ok
If $f(x) : A \to B,$ do you write $f(x)(a)$ or $f(x)a?$
Invictus
f(x)(a)
yeah thats what i thought but im seeing the latter notation in this book im reading
yeah
I'd sometimes write f(x)a if f(x) is linear
Have yall watched the new 3b1b vid?
which one? the one about generating functions or did he somehow make a new one thereafter?
"olympiad level counting?"
Yes that one
A question I though if was what is the largest number that is divisible by five that can be made by summing integers 1-2000?
I haven’t seen it yet but I probably will
You can at least say you’d sum all numbers from 5 to 2000 right
the sum of all of them
True
Can every multiple of 5 from 5 to (the sum of all of them) be made from the integers 1-2000?
yes
the set of numbers that can be made by summing numbers ${1, \dots, n}$ is ${1, \dots, \frac{n(n+1)}{2}}$. You can show this by induction on $n$
mniip
this is because it is never the case that $n > \frac{n(n+1)}{2}$ for integer $n$
mniip
Cool, thanks
I stated my claim specifically enough
Interesting, going back to the problem from the video. I was thinking the answer is also the number of distinct partitions for every integer from 1 to 2,001,000 that is also divisible by 5. But as the numbers get larger some partitions would use numbers larger than 2000.
anyone here who uses wsl2 ?
anybody watch this ever? https://open.spotify.com/episode/5fu4hHfMVHdaU2EkJmU9F8?si=b7b208b55c8f40ea

*listen
@sleek wing
I have listened to Dreaming Pt. 3 about 9 times in the past 2-3 hours and Noise Zero about 4-5 times
Edit: My wife says she also likes these songs and your style in general
Aah, every time I open this channel I get a million popups about enabling DRM.
Chixen
is this something i am too poor to understand?
It's like a media rights thing. You don't want DRM.
How wholesome
Such a wholesome chungus
I don't have a wife but I also like your songs
freshman: 9th grade
sophomore: 10th grade
junior: 11th grade
senior: 12th grade
and then college
like thas how it goes
thats high school?
yup
Whats middle school for yall?
6th - 8th grade
no school names we call it "jr high"
yup
wth
culture barrier lol
ikr so wait what grade are you in
So we finished 10 now, ill be 11 just finishing summer break
15
Where in ur 20's
nahhhh that's like college age
i'll be 18 or 19 when i graduate
that's how it usually goes in the united states
how bout in your country
well so u graduate elementary at 6th
Then in ur 7-10 yeats
years*
u get something called advancing
they give u some medals and shit every year
dam
then u reach 10
where u have a like top of all - class
Valedictorians
Then after that u graduate high school
then at ur senior high u pick a career
11-12
WHAT
THAT'S NOT FAIIIIR
If u wanna take law ur gonna go to this field where they teach u about humanities and stuff
then if u wanna take engineering
Theyll take u to a field where its all mathematics, calculus, and physics
Then u can take general field. Which studies all of them and basically how to kill urself
Undecided people takes those
is there one for like health and doctor stuff?
Ye
that's awesome i wish the united states has that
i wish my school let me take more of the classes i wanna take and less of the ones i don't
SAME
it kinda sucks tho
but for me a big gigantic nerd i'd want to do that shit
Coz in our high school its night abd day
oh hell naw
that i can't stand night classes suck
at my school there's like only 6 classes you can take + a zero period
6?
Wtf?
ikr
i can't bro
We have likw fucking 10
at my school we're very restricted with what classes we can choose, especially with academic acceleration so i'm forced to take classes i want to take during the summer
same
i saw the classes offered to my friend who's going to boarding school next year to the US and i was so jealous
i go to a catholic school and there's a mandatory THEOLOGY CLASS i have to take
his school offered abstract and linear algebra in high school
Damn thats pretty bad
theology is like study of religion
lol
Omg
Jesus Christ
this is why i'm doing something called concurrent enrollment
do concurrent enrollment it's taking classes at a community college and getting college credit to learn more
i wish i could take classes in a local community college or smth as well, but i live in a foreign country where it's difficult or just not possible at all
at most you can get like 24 classes done in a year if you want to die
NOOO
Haha im not much of a math nerd im only interested in probabilities but im an astronomy nerd
astronomy is wicked
i love astronomy
you should be an astrophysicist or something
ikr i'm asian
they dont do that shit
aerospace engineering?
Yea there's no aerospace company here lmfao
broooo
Also they kinda extremists or something
well probably DOCTOR or LAWYER
I said i want electrical engineering
And prolly throw in coding
So i know how to program shit too
They said no
Like what
Thwy spent all my high school asking me what i want
bro that makes a shit ton and that's a highly respected job
then when i said something haha they didnt want
Ikr
im so mad
goddam
are you gonna move abroad or something?
I dont want to
wait what they recommend
Accounting lmfao
nahhhh
i'd rather be an engineer than an accountant
ikr
400$ a month
USD?
Yea
PH
yo i'm filipino
Yo fuck you take me there too
my parents came from the philippines
?
ohhh
OFW's
yeah they worked hella hard
true
My dad was one
And my brother is too
but theyre gonna move out soon
and my dad retiring soon too
So its all up to me now
just follow your dreams and be an electrical engineer
you'll be swimming in money with a good job
and your parents will be proud thas all parents want tbh
not mine
What does your dad want you to be?
filipino parents be filipino parents
accountant lol
Wow
lmao
I wanna be an electrical engineer and know programming
my dad wants me to be an accountant
My brother wants me to be a pilot since ive always told him when i was a kid i wanna be one
well when i was a kid i said i wanted to be the president of the united states
Man you should just go with the thing you want to do
like yeah the decisions we make as kids are kinda stupid tbh but
just go with what you want to be
wait wait i know this is off topic but is it true that there's a class just for "jose rizal"
cuz my parents said that they had to take it back when they were in school in the 1980s
Yea
there is
i forgot
Can u speak filipino?
There is and its not just jose rizal haha
Maybe it used to be
hell naw
Its a subject called "Filipino"
my parents never bothered to teach me
but back then i really wanted to so that i can understand what they're talking about
Reasonable maybe they didnt want pressure
probably
wait so it's just filipino history right
Hell nah
filipino history and literature?
oh that's weird
in the US and like every single other english speaking country we have different subjects for those
english: (literature, grammar, rhetoric, writing)
US history
world history
we call it "Social Studies"
that's what we had in uh
elementary school
Damn
you take them in different years tho
Oh goddamn we had it from elementary to high school 10
english is mandatory for all four years in HS
US is 11th grade
world history is 10th grade
so yeah i'm taking world history next year i'm dead
world history?
learning about the entire world
Not just world wars?
it's like
guys
1200AD to present day
how do I find the matrix of a linear transformation?
i have no idea
oh hell naw i don't even know what you just said
uh go to #linear-algebra
it's a movie i think
but yeah and there's this system in the united states called "advanced placement" or AP
yup
mom is kampagnagnapnaggnapn however you spell it
dad is ilocano
however you spell it
ikr
it's so hard to say it idk how my mom nails it every time
my dad can't even say it
AP classes are dogshit they're college classes put into high school
and if you take them you get college credit and stuff
Like exams?
they're classes + exams
AP?
yeah
Thats weird
like AP world history
AP us history
AP literature
AP english
AP calc AB/BC
AP stats
those are some classes
and then there's honors classes where they just give you more homework and make you want to die
lmao
US school system sucks btw
Better than us atleast
really?
yea
dam
bro tell marcos to put an upgrade
Wait gimme a min ill be back
He will
lmao
wait actually???
bet
Back bro @shrewd bobcat
yoyo
idk why 15 MILLION stupidos voted for someone who cant even lead
bro who was that guy
woman*
oh...
Victims of information
leni robredo
my parents said marcos was good back then
They are
Our country went to hell when the "revolution" took place
not even a revolution haha
no
bro this is interesting
learning about another country's history and shit
Well so
Yk about the martial law
Thats great
so like 1960's
Marcos ran, and won, and ran, and won, and ran, and won
just by looking at this yk how good life used to be
my parents say that he made the philippines into like an economic powerhouse or something
He dis
did
dam
so then his last election
He won against "Corazon Aquino"
An anti martial law person
then corazon threw a tantrum and rallied at the government and shit like that
If we didnt declare martial law PH woulda been communist controlled ngl
mhm it still exists today here
and they're mostly negative
socialism... it's okay if done correctly but like the nordic countries and the people don't have enough money
but yeah marcos is good
i mean the ideas are cool
But well
Yea
Groundbreaking votes too
31M
i wonder how much more if people at my age can vote
oh american politics is way worse than that
lmfao i can see that
like republicans raid the capitol building
hahaha
just get Obama back bro
and our president is a joke
nahhh
people might hate me for this but trump was actually good
he is
gas prices lowered down and shit
yea holy shit xD
a gallon?
oh damn here too
the car my parents use is like 14miles per gallon
my dad's work is like 40 miles here and back
Lmfao wtf
yeah lower housing prices
that's the cost
if gas is $3.50 again i'd fucking cry tears of joy
Oh yeah its fucking bad haha
Duterte fixed that shit
that's good
my parents said that filipino traffic sucked back then
It used to suck 6 years ago before duterte took over
damn
traffic here is basically nonexistent in my commute
never here
my parents drive me to school like 80mph
that's how smooth the traffic is
but like los angeles traffic sucks ass i've waited 2 hours in a highway once
ikr
but some dumbass people like drive slowly when there's no one
and that causes slow traffic
wait the philippines completes school in summer too?
Yes
wow
Lmfao
whas ironic
private you have to pay
but like how much are the private schools
my dad went to private school
i think it's called "san tomas" or something in manila
yes
lol and i thought yall have good salaries
we do
Hoe much
oh a month
idk how much
i only know a year but i guess divide
17000
?
some private schools in america are like $60000 per year
Jesus
Damn
my friend is going to one
wait you live in the united states?
Are their parents billionaires or something
No I don’t, but I don’t need to live there to see that those prices are insane
my friend goes to "harker school"
Ngl the name sounds like a “rich kid” school
210k a year?
legit public schools are better value
I’m not going to lie, it sounds like absolutely atrocious value
But I suppose if your parents make like a hundred million or something it’d be a drop in the bucket for them
@shrewd bobcat so one of ur parents makes in a month, 5 month of work here...
like a penny's worth
Yeah
?
i guess
oh shit
Salary here around 20-25k on average
Ultra rich ppl just look weird to outsiders I suppose
Monthly
no way
PHP > USD calculator
holy shit
wait yaeso can't you just walk to school or something
Then theres jobs where u make 40k
or work
Depends
Oh me? Nah i have to drive to the cityhood
jesus
in the philippines my grandpa owned a lumber company and he was very rich
he's still hella rich
just searched it up
average income united states is
50k-60k
per person
What’s median income
Average is going to be ultra skewed with all the billionaires
31k
Huh
lol it is ultra skewed
what country has the highest median income
lol luxembourg with 44k
Luxembourg is quite urbanized and also serves as a tax haven for a lot of rich people, so this isnt surprising
i am surprised monaco isnt higher
Median?
yeah
whats that
i cant find a site that actually reports monaco's median income
so it might just not be reported anywhere
since intuitively i would expect it to be the highest of anywhere but the vatican (which doesnt really count)
if you take like a set of numbers
also divorce isnt legal here
and put them in order
midpoint of the ordered data set
2 7 4 8 2 5 7
simpler definition
but i'll continue anyways for an example
put em in order
2 2 4 5 7 7 8
Ic
take the middle which will be 5
so if a country's median income is $40000, that means 50% of people make at least $40000, and 50% make less than that
essentially
median: 5
its more stable towards outliers than the average
yes yes
if you're gonna have a data set with like
2 5 2 1 5643795634798578934
it's gonna be hella skewed
i hate probability and stats
I fuckin lovebit
i find calculus, trig, and algebra way more entertaining than probability
Isnt calculus related to probability
No offense but i hate trig so much haha
all i know is differentiation
probably a tiny bit
but i don't even know the other kinds of calculus if they relate
or the applications of differentiation
trig is weird
it is
it takes time to understand
and you have to memorize so much stuff
in such little time
like sum, difference, double angle, half angle, even-odd, cofunction, pythagorean
all that shit and the unit circle
at least you repeat it in precal
@shrewd bobcat how long did u guys go theough trig
last 3 months of the year
Don’t you guys have formula sheets?
All of them?
not all of them
Us? Hell nah we have books we cant understand
no
i just did them myself cuz i'm a huge fucking nerd
4 months?
we went through everything except cofunction, even-odd, and pythagorean
Goddamn we did all of those haha
I dont remember a single one
If i remember
I dont know what its called
i don't even remember any formulas
lmfao same
all i know is that sohcahtoa
I can prolly recognize
sin cos tan csc sec cot
oh hell nah i dont remember shit
π
Well atleast i know probabilities?
statistics is its own other subject
shiit in my class
Rip
i had to learn everything myself in order to pass the class
im prolly gona watch some trig in yt
lmao watch the organic chemistry tutor
all his videos on trig are informative
Sin cos tan shit?
yes
Cool thx
np i sometimes watch him if i'm having big big trouble in math
I think i watched him in dividing polynomials
he's also good for
biology
biochem
chemistry
physics
same
cuz i kept on skipping school and didn't know what the fuck was going on in class lmao
i managed to pass tho that's all that matters
Haha well it takes me like an hour to understand shit my own
Without teachers and stuff
oh i need teachers
if i don't have a teacher giving me a lecture
i'm dead
i can't just read off a book
i need a teacher please goddam
those people who can read off a book and absorb it... HOW???
i didnt learn shit coz we have learning sheets
did your teacher not do shit?
We have online classes but family reasons on why i cant attend
Whats that
yeah that's what it's called (on-campus and online classes)
that's hybrid learning
we had that during COVID but now we don't
why? how many cases of covid are there?
Like uhm lemme search
theres 130 today, very few
In total 3.70M cases and like
60k deaths
bro then why only online?
Politics, good question
Uhm idk but next school year its all normal again
After summee
summer
Everyones back
excited?
Ofc
hell yeah
it's hell doing that
i did that with chemistry once
holy shit i didn't learn shit
ikr
imma need a goodass teacher and a lab please
and thank god my teacher next year for chemistry is a PHARMACIST
so he knows a SHIT FUCK TON of chemistry
and everyone says he's hella good and i'm so psyched to have him
damnnn
everyone in 10th grade last year hated chemistry cuz it was so hard
4am
U lucku
i don't even sleep that much i'm sleep deprived and my sleep schedule's all over the place
yes
Its uhm 6:45 pm
no but there are Catholic schools here and i entered a Christian school
do you have to go to religion class 💀
yes
haha
but they only teach morals
and some religion
nahhhhh
LMFAO
abstract shit and doctrine
dogmas and like what they do in the vatican
like st mary achool
legit 8th grade theology was learning about the whole history of the church
Hahaha
Well here we learn about morals our whole school life
but it's so archaic and old
bro
good morals 🙏
whether it's justified?
what
oh
Give to receive from god
Be good to ur parents
Then they teach some bible stuff
On crhistian school
On Catholics
Idk
Lmfao
i mean by went through the bible we read some passages from every single book
We only have one book i think
nonono like bible books
like genesis, exodus, matthew mark luke john acts
They are? Wow didnt know that
fdsjkl
anyways
and then we had a textbook that explained what that passage said
and simplified it
ohhh
but its annoying when
then it's free credit
Not rlly
bruhhhh
lmao
Do u wanna read long ass stories? Like very long
nah here we call it english class
where it's a clusterfuck of grammar, literature, and writing
lol
Yea holy fuckin shit
If its like one for in the USA
Its two heee
Here
goddamn
it must be hell for you
yes yes yes and yes
Damn
i took PE and health last year
U take
and music
art i don't have to take it
really?
you have to take those. Music arts pe and health, all from elemntary til u finish high school
All of them
it doesnt matter if u suck at arts
Youll still take it
Youll still paint haha
bro it's mandatory???
YES
haha
On normal time
What time yall finish class
Like
On normal
Schedule
start and end at
my school-life goes from
7:30am - 2:30pm
Goddamn
Mine goes 8:00 : 3:45
And we barely get breaks every subject
The only break we get is recess and lunch
that's hell
Yea
yes, 15 minutes
bro yall get breaks in between subjects haha
like 4 minute breaks to get between classes
yes
Here the teacher moves
no fair
We just sit
i wish i wasn't late to class
legit i sprint class to class
YOU GET FLOORS???
YOU DONT GET FLOORS?
never
What school is that wtf
floors are rare in the united states
usually at most 2 floors
Here its around 2-5
i mean stories
Coz lot here is expensive as fuck
Yeah that
More expensive than the house itself
so build up build up build up
Yes
legit if your highschool doesn't have a football field in america you're considered a small school
What football
Which football
every high school has
a football field
classes
baseball field
